Well if they start doing simultaneous (or at least, close to) releasing starting with Cold Steel 3 that would be the ideal scenario.At this point i'm assuming and port by Xseed is just them future proofing things. PC games have legs if the port is good and a good port also means porting to other platforms is easier/cheaper. Which is better than constantly porting to new consoles with no PC port.
It's essentially what Capcom has been doing this gen with their ports after all.
